the ARS confirms a first autochthonous case

While initially the dengue virus was suspected, the ARS explains that the patient was infected with the Usutu virus.

This virus is of African origin. Health authorities indicate that it mainly circulates among birds, mainly blackbirds and sparrows. Unlike dengue fever, the Usutu virus is transmitted by the common mosquito and not by the tiger mosquito, which has invaded New Aquitaine for several years. “The spread is classic: the mosquito bites a bird carrying the virus, then a human being. The Usutu virus is not transmitted from man to man, nor from man to mosquito, ”explains the ARS.

Not a real danger

It was identified for the first time in humans in Europe in 2009 and in France in 2015. But the health authorities reassure, the infection is most of the time asymptomatic or slightly symptomatic. The person who contracted the virus had flu-like symptoms.
